Amnesia is a massive detriment to your life. You lose friends, your job, sometimes your significant other. I can only imagine how much harder it would be for a child. Who does she have now? Neil and Garry? Well hopefully that pit of cushy foam will make her feel a little better.

P.S - If I it someone with my car, I don't think I'd be pushing said victim into a death pit.

So she's either trying to lighten Joy's mood by diverting her thoughts with making her get angry at her or she's simply just taking the chance to pay her back for the times she did it, but that would be just too cruel. :P
